acros only at night

Most acroporidae will fully extend their polyps at night to feed since there are less predatory fish or they aren't active. Specialized polyp feeders hide when the lights go down so the polyps use the darkness to extend, respirate and feed. At night, more plankton go into the water column triggered by the calmer seas and slight shift in water temps and upwelling currents.
If you have a tank full of sps, wait until 3 am one night and turn the lights on- you'll be amazed to see the polyp extension and critter activities you'll find, you'll stare at your tank and find new things (I found an 11 inch fireworm and a gorilla crab in my old tank)

i pretty certain none of my fish are bothering them. they are all model citizensPhyl said:
in the tank are 2 anthias, maroon, coral beauty (is pretty well behaved other than an occasional nip at my carnation) both flavors of mandarin, engineer goby, lawnmower, blue devil, purple firefish,yellow tang.ive never flipped on the lights, but i do have night vision goggles i play with and a red light and you're right, there is some crazy stuff that goes on at night in there. ive found some monster bristle worms creeping around in there. the comment on calmer seas makes me think i should set my power heads on timers? i have a coralife 1300 and 750 that are on 24/7. should i set timers to have them switch on and off throughout the day and night? it does make sense since in the ocean the tides and swells change up. if so, would hourly or 6 hr changes be good?concept3 said:
when I used to have 4 maxijets, I would set all 4 "on" during the day. At night, I went down to only 2 which were on opposite sides of the tank. Plus, the calmer night mode is good for everyone, fish included.
During the day, random is good, any and which combination. Most reef crests see more turbulent and random water than lets say, deep water reefs which see more ebb and flow. The kinds of corals you keep should determine that, softies for calmer....sps for more.
